Going shopping with John Idzik must be painful — the man takes his time.

As of early Wednesday night, the Jets general manager still had not signed a free agent from another team as big-name players signed on elsewhere.

There was some movement Wednesday as the Jets played host to Broncos free-agent wide receiver Eric Decker and Seahawks free-agent tackle Breno Giacomini, according to sources. But there was no announcement of any deals getting done.

The first 24 hours of free agency were a spending frenzy, with the Broncos leading the way. But the Jets sat on their checkbook, watching players sign elsewhere. Some say this is a wise strategy in free agency, but the Jets have a ton of holes to fill and are nearly $40 million under the salary cap. A few early moves were expected.

Decker could address the Jets’ biggest need. The team desperately needs to upgrade its wide receivers to provide quarterback Geno Smith with some weapons. Decker, who turns 27 on Saturday, has posted back-to-back 1,000 yards seasons with the Broncos.

He is considered the top wide receiver available, but there are questions about how he would fit with the Jets. One league source said he is not what the Jets need because he struggles against man-press coverage and that is what the Jets see often because of their run-first offense. He pointed to Decker’s one-catch performance against the Seahawks in the Super Bowl as evidence.

Many people also believe Decker’s production is a result of playing with quarterback Peyton Manning and he will not produce with a lesser quarterback.

“Peyton is getting him paid,” the source said.

There are questions about his value, too. The going rate for the top receivers has been around $6 million per year. Anquan Boldin (49ers), Golden Tate (Lions) and Jeremy Maclin (Eagles) all got deals in that ballpark. Decker is likely looking for more than that since he is considered the top receiver available, but it is unlikely the Jets would go too much higher than that.

A source said ideally the Jets would like to sign two wide receivers and add a potential No. 1 receiver in May’s draft. This draft class is deep at wide receiver and a source said that the Jets will not overpay in free agency for that reason.

Giacomini has been the starting right tackle for the Super Bowl champion Seahawks for three years. Idzik was a member of the Seahawks front office when they signed him away from the Packers. Giacomini missed seven games last year with a knee injury but returned in time for the team’s run to the Super Bowl.

The Jets need to replace starting right tackle Austin Howard, who signed with the Raiders early Wednesday morning.
